  • Interface devices for instruments in communication with implantable medical devices
    Patent number: 6580948
    Abstract: External medical instruments that are in physical contact with a patient's body to communicate with or test the function of implantable medical devices (IMDs) implanted in the patient's body or to measure a physiologic condition of the patient's body and capable of communicating with other medical instruments or systems located at a distance from the patient, and, particularly, safety systems for protecting the patient from harm due to hazardous electrical signals or potentials. The external medical instrument operates pursuant to an instrument operating system that processes and generates electrical signals. A patient cable is coupled to a patient's body for transmitting electrical signals from the instrument operating system to the patient's body and for receiving electrical signals from the patient's body. A data cable extends to a remote instrument or a network, e.g.
